European Association of Echocardiography: Research grant programme
No full textThe European Society of Cardiology (ESC) offers a variety of grants/fellowships to help young professionals in the field of cardiological training or research activities throughout Europe. The number of grants has significantly increased in recent years with contributions from the Associations, Working Groups and Councils of the ESC. The European Association of Echocardiography (EAE) is a registered branch of the ESC and actively takes part in this initiative. One of the aims of EAE is to promote excellence in research in cardiovascular ultrasound and other imaging modalities in Europe. Therefore, since 2008, the EAE offers a Research Grant Programme to help young doctors to obtain research experience in a high standard academic centre (or similar institution oriented to clinical or pre-clinical research) in an ESC member country other than their own. This programme can be considered as a valorization of the geographical mobility as well as cultural exchanges and professional practice in the field of cardiovascular imaging. The programme has been very successful so far, therefore in 2012 the EAE has increased its offer to two grants of 25 000 euros per annum each.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Tricuspid valve morphology and function evaluation by transthoracic real-time three-dimensional echocardiography
No full textTricuspid valve (TV) morphology and function evaluation plays a key role in several cardiac diseases, including left-sided valvular diseases and heart failure. However, TV is structurally complex and, differently from aortic and mitral valves, cannot be visualized in a single two-dimensional echocardiographic view, neither transthoracic nor transesophageal (i.e., simultaneous imaging of the three TV leaflets and their attachment to the annulus is not feasible). Conversely, real-time three-dimensional transthoracic echocardiography allows complete visualization of the TV apparatus from multiple views. This can lead to an improvement of our understanding about the pathophysiological mechanisms underlying TV diseases and functional tricuspid regurgitation, and may suggest new surgical techniques in order to improve surgical outcomes. The present review focuses on the state-of-the-art of real-time three-dimensional transthoracic echocardiography in TV morphology and function evaluation with its clinical applications and limits
[Reporting echocardiography exams with the G8-Cardio ANMCO software]. FT Refertazione dell'esame ecocardiografico con il software G8-Cardio ANMCO.
No full textBACKGROUND: The availability of a common computerized program for echocardiographic study archiving and reporting at national and/or international level could make it possible to standardize the echo reports of different echocardiographic laboratories, and to use the wealth of data thus obtainable with echocardiography, and to exploit its capillary territorial distribution, with the aim of collecting echocardiographic data in a standard format for epidemiological, scientific and administrative purposes. METHODS: To develop such a software, an ad hoc joint National Association of Hospital Cardiologists and Italian Society of Echocardiography task force worked in conjunction with the Italian Branch of Agilent Technologies to standardize the phraseology of accepted echocardiographic terms and of the quantitative parameters derived from transthoracic and transesophageal echocardiographic examination at rest as well as during exercise and pharmacological stress, and to develop an ad hoc software. This echocardiographic study archiving and reporting program is part of the whole G8-Cardio ANMCO software developed to computerize the whole cardiological chart. The software has been developed by Agilent Technologies to provide a fast, easy-access and easy to use report generator for the non-computer specialist using DBMS Oracle 7.3 database and Power Builder 5.0 to develop a user-friendly interface. RESULTS: The number of qualitative and quantitative variables contained in the program is 733 for echocardiography at rest, while it depends on the stressor and on the length of the examination for the stress echo (dipyridamole 214-384, dobutamine 236-406, exercise 198-392). The program was tested and refined in our laboratory between November 1999 and May 2000. During this time period, 291 resting and 56 stress echocardiographic studies were reported and recorded in a database. On average, each resting echocardiographic study lasting 10 +/- 4 (range 5-17) min was recorded using 50 +/- 11 (range 33-67) variables and 41,566 bytes of hard-disk memory space. Stress echocardiographic studies, each lasting 7 +/- 5 (range 5-21) min, were recorded using 143 +/- 74 (range 38-194) variables and 38,531 bytes of hard-disk memory space. CONCLUSIONS: To our knowledge this software represents the first experience of a common computerized program for echo archiving and reporting carried out at national level
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
